Fig 4 — There are four bar charts in Fig 4. The chart with the blue bars show average detection thresholds for glucose in mM. The chart with the red bars show average detection thresholds for fructose in mM. The chart with the purple bars show average detection thresholds for MDG in mM. The chart with the green bars show average detection thresholds for sucralose in μM. Each chart contains three bars. From left to right the bars show: 1) Detection threshold, 2) Detection threshold with 20mM NaCl added, 3) Detection threshold with 20mM NaCl and 0.2mM phlorizin added. All treatments were paired with water rinses between stimuli. Twelve subjects participated in the fructose and sucralose testing and eleven subjects participated in the glucose and MDG testing. All subjects completed two replications. Error bars are standard errors of the mean. * indicates a significant difference, p < .05, ** indicates a significant difference p < .001.
